Answer: Let the width of the park be; w

width=w

length=3w

and let the distance between opposite corners of the park be; d

then the expression is; (w)squared +(3w)squared = (d) squared

width=w

length=3w

and let the distance between opposite corners of the park be; d

then the expression is; (w)squared +(3w)squared = (d) squared

A car sales man sales 5 cars this month. Each car cost about $34,000. If he makes 5% commisson on his total sales, How much money will he make this month?

Answer:

8500

Step-by-step explanation:

If 5 cars each costing $34,000 were sold you would add those together which equal 170,000 and then find 5% of 170,000 which is 8500 so if the car sales man earns 5% he got $8500 this month

Which expression represents the volume of the cone that is times the volume of the pyramid that it fits inside? (2r2h) (4r2h)

The expression represents the volume of the cone that is times the volume of the pyramid that it fits inside is Pi/4(4r²/3).

We have given that the expression represents the volume of the cone

that is times the volume of the pyramid that it fits inside

(2r^2h) (4r^2h)

What is the formula for the volume of the cone?The formula for the volume of a cone is ⅓ r^2h cubic units.

where r is the radius of the circular base and h is the height of the cone.

Therefore from the given we get the volume of a pyramid is Pi/4(4r²/3).

A binomial is also a polynomial

True

False

ANSWER

True

EXPLANATION

Polynomials can be classified based on the number of terms.

A simplified polynomial with only two terms is called a binomial.

Note that the following are polynomials that are binomials:

etc.

The above statement is therefore true.

In a study to determine the relationship between self esteem and eating, subjects had been randomly divided into two groups. One group of subjects were individually told something intended to boost their self esteem while in the other group subjects were individually told something intended to lower their self esteem. Each subject was then individually led into a room alone and asked to count the number of chocolate chip cookies in a very large container and told they could eat as many as they liked while conducting their count. Researchers then counted the number of cookies eaten by subjects in each group. Which of the following statements is true regarding this study? Check all that apply.

This study is an observational study.

This study is blind.

This study is an experimental study.

The treatment was the number of cookies eaten.

ANSWER:

The correct answer is

-This study is blind.

-This study is an experimental study.

STEP-BY-STEP EXPLANATION:

This study includes a controlled treatment (in this manner it is an investigation) and subjects didn't have a clue about the idea of the treatment so it is visually impaired.

300 children 3/5 are boys how many are girls

So,

There are 300 children.

One-fifth of 300 is 60 (60 times 5 = 30).

(Five-fifths minus the boys) of the children are girls.

Multiply 60 by 2.

60 * 2 = 120

There are 120 girls.

There are 300 children.

One-fifth of 300 is 60 (60 times 5 = 30).

(Five-fifths minus the boys) of the children are girls.

Multiply 60 by 2.

60 * 2 = 120

There are 120 girls.

Well if you divid 300 and 5 you get 60. So for every 1/5 is 60. So if you do 60 times 3 equals 120. So then you subtract 300 minus 120 and get 280. So there are 280 boy and 120 girl.

Arleen has a gift card for a local lawn and garden store. She uses the gift card to rent a tiller for 4 days. It cost $35 per day to rent the tiller. She also buys a rake for $9. A. Find the change to the value on the gift card. (Question #1)

B. The original amount on the gift card was $200. Does Arleen have enough to buy a Wheelbarrow for $50? (Question #2)

Answer:

Step-by-step explanation:

Arleen has a gift card of the amount = $200

The total cost to rent the tiller for 4 days and a rake for $9

= ($35 × 4) + $9

= 140 + 9 = $149

A. Now the balance on the gift card = $200 - $149

= $51

B. Arleen have $51 in her gift card so she has enough to buy a wheelbarrow for $50.00.

35 • 4 = 140 + 9 =149 for rent and rake

200 - 149 = 51 left on gift card. Yes she has enough to buy the wheelbarrow.

200 - 149 = 51 left on gift card. Yes she has enough to buy the wheelbarrow.

Which of the following equations have graphs that are parallel to the graph of the equation y=-3/2x+8? I. 3x + 2y = 10

II. 2x − 3y = 9

III. 6x + 4y = 28

IV. 3x − 2y = 8

I and III only

II and III only

IV only

III only

Parallel lines will have the same slope, but different y int

y = -3/2x + 8....slope = -3/2....y int = 8

(I) 3x + 2y = 10

2y = -3x + 10

y = -3/2x + 5....slope = -3/2, y int = 5....this IS parallel

(II) 2x - 3y = 9

-3y = -2x + 9

y = 2/3x - 3...slope = 2/3, y int = -3....is not parallel

(III) 6x + 4y = 28

4y = -6x + 28

y = -3/2x + 7...slope = -3/2, y int = 7....this IS parallel

(IV) 3x - 2y = 8

-2y = -3x + 8

y = 3/2x - 4...slope = 3/2...y int = -4...this is not parallel

solution is : I and III

y = -3/2x + 8....slope = -3/2....y int = 8

(I) 3x + 2y = 10

2y = -3x + 10

-3y = -2x + 9

y = 2/3x - 3...slope = 2/3, y int = -3....is not parallel

4y = -6x + 28

y = -3/2x + 7...slope = -3/2, y int = 7....this IS parallel
